IMPROVEMENT iN WEATHER-STRIPS.

Specification forming part of Letters Patent No. 175,997, dated April 1l, 1876; application'led December 24, 1875.

ing drawing, and to the letters of reference marked thereon.

This invention relates to a weatl1er-strip to be attached to the bottom ot' a door, or at the side of a window-sash, to prevent the entrance of air, dust, 85e.; and consists in means whereby the packing or iiexible strip used to forni a close joint oi'ers no resistance to the opening` of the door, and when applied to windowsash, to its elevation or depression.

In the further description of my invention, which follows, due reference must be had to the accompanying drawing, forming a part of this specifica-tion, and in which- Figure l is a view of a door in a closed position and having attached thereto my inlproved weather-strip. Fig. 2 is a View of the same, with the door open. Fig. 3 is a back view ot' the invention, and Fig. 4 a cross-section of the same.

Similar letters of reference indicate similar parts of the invention in all the views.

A represents a door, to the lower edge of c, which holds the packing or iiexible strip d.

The plate c is slotted, the slots, which are represented by e, being inclined with reference to the edges of the plate c and metallic strip a. The plate o is held within the space b by means ot' the bolts or pins e. The position ot' the folded plate c and iiexible strip d, or that occupied by them when the door or windowsash is open, is shown in Figs. 2, 3, and 4, the said parts being iniiuenccd to occupy such position by means of a spring, f, in connection with the pin g, which serve to elevate them and withdraw the flexible strip from contact with the floor or door-frame. In closing the door the projecting end c of the folded plate c comes into contact with some part of the door-frame or a plate fastened thereto, and is forced in the direction of the slots, bringing the edge ofthe flexible strip d in contact with the door or bottom of the door-frame.

In the adaptation of my invention to windows the operation is substantially the same.

I am aware that weather-strips rising and falling by means of springs in diagonal slots are not new, and such, therefore, I do not claim; but

What I claim as my invention and wish to secure by Letters Patent of the United States,

The folded metallic clamping-strip c, provided with the diagonal slots e, rubber packing cl, and pin g, combined with the offset metallic plate a, pins c', and spring f, as and for the purpose specified.

In testimony whereot'l have hereunto sub scribed my name this 2d day of December, in the year of our Lord, lt`75.
